 The main system is completely AC powered, the battery only to be used for standby mode, the battery provides 12VSTB if there is no AC input, the system can’t be turned on.

 Only if there is AC input, 12VSTB power will generate 5VSTB and 3.3VSTB.


 When system is shut down, disconnect the AC power, when the battery is in use, the battery management will shut down the 5VSTB and 3.3VSTB output, that is to say, the power management itself will be powered off until AC powered on.

 On standby mode, disconnect the AC power, when the battery is in use, the battery provides

12VSTB power, and transfers into 5VSBT and 3.3VSTB for system use in standby mode.

5.5.2.1 Resolution

 transverse resolution

Test Step:

1. Cover the scan surface of the phantom with water or couple gel, gently contact the probe with the scan surface, making the transverse resolution testing targets to be displayed around the midline of the image.


2. Adjust the focus point focuses at the position where the transverse resolution testing targets are displayed.

3. Adjust parameters like gain, dynamic range, TGC, making the background tissue unseen, just displaying the target image clearly.

4. In condition that the transverse resolution testing targets are horizontally displayed, record the minimal distance of two targets that can be clearly recognized.

5. Repeat the operation above for the transverse resolution testing targets at other depths.

As shown in figure below.

 Axial resolution

Test Step:

1. Cover the scan surface of the phantom with water or couple gel, gently contact the probe with the scan surface, making the longitudinal resolution testing targets to be displayed around the midline of the image.

2. Adjust the focus point focuses at the position where the longitudinal resolution testing targets are displayed.

3. Adjust parameters like gain, dynamic range, TGC, making the background tissue unseen, just displaying the target image clearly.

4. Record the minimal distance of two longitudinal resolution testing targets that can be clearly recognized.

5. Repeat the operation above for the longitudinal resolution testing targets at other depths.


NOTE:

1. When using the convex probe, keep the transverse resolution testing targets to be displayed near the midline.

2. When using a linear probe with steer function, do not turn on the steer function when perform the transverse resolution test.

3.

Zoom in the region where the targets located if necessary.

4. The diameter of the target point at a certain depth is equal to the transverse resolution at the depth.

5.5.2.2 Maximum Depth

2. Set the system display depth according to the expected maximum available depth of the probe in use.

3. Adjust the focus point to the deepest, and AP at the maximum value.

4. Set gain, contrast, TGC at a greater value, but no halation nor defocus is allowed.

5. Record the depth of the furthest target (the target can be seen clearly).

NOTE:

1.

Increasing the gain will also increase the noise, and echo may be covered.

2. When using a linear probe, please completely contact the probe with the scan surface, no side clearance is allowed.

3. When using a convex or phased-array probe, make the axis targets to be displayed at the middle of the scanning image.

4. When system is not frozen, the fast field target information may be similar to that of the noise, do not use this target.




5.5.2.3 Geometric positioning accuracy

 Longitudinal geometric positioning accuracy

Test Step:

1. Do adjustments as the way in testing the maximum depth.

2. Record the distance by 20mm each segment on the longitudinal targets line using the measurement caliper;

3. Select the value with the greatest error (to 20mm), calculate the accuracy using the formula below

1. The measurement caliper should be positioned at the upper edge of the

NOTE:

target, not the middle nor the lower edge.

2. The scanning plane should be vertical to the target line, that means the scanning plane is parallel with the cross-section of the phantom


 Transverse geometric positioning accuracy

Test Step:


2. Adjust the depth, making the transverse targets to be displayed in the image.

3. Adjust the focus point to be posited beside the transverse targets (the standard is not clear)


4. Adjust parameters like gain, TGC, making each transverse targets to be clearly displayed.

5. Record the distance by 20mm each segment on the transverse targets line by using the measurement caliper

6. Select the value with the greatest error (to 20mm), calculate the accuracy by using the formula below

NOTE:

1.

When using a linear probe, record the transverse distance by segment.

2. When using a convex probe, all transverse targets should be displayed integrally in an image.

3. The measure caliper should be posited at the upper side or lower side of the target center.



5.5.2.4 Blackout Area

Test Step:


2. Adjust the depth at a lower value, and set the focus at the nearest place to the scan surface.

3. Decrease the value of parameters like AP, Gain until the background noise just can be seen.

4. Record the smallest depth of the target that can be seen clearly, that value is the blackout area value.

NOTE:

1. When using a linear probe, please completely contact the probe with the scan surface, no side clearance is allowed.

2. For convex probe, the targets in the blackout area should be positioned on the midline of the scanning plane.

Appendix A Electrical Safety

Inspection

The following electrical safety tests are recommended as part of a comprehensive preventive maintenance program. They are a proven means of detecting abnormalities that, if undetected, could prove dangerous to either the patient or the operator. Additional tests may be required according to local regulations.

All tests can be performed using commercially available safety analyzer test equipment. These procedures assume the use of a 601PRO

XL

International Safety Analyzer or equivalent safety analyzer. Other popular testers complying with IEC 60601-1 used in Europe such as Fluke, Metron, or Gerb may require modifications to the procedure. Follow the instructions of the analyzer manufacturer.

The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is emphasized as a mandatory step if an approved agency status is to be maintained. The safety analyzer also proves to be an excellent troubleshooting tool to detect abnormalities of line voltage and grounding, as well as total current loads.
